The bonding and anchoring function between the cold rolled ribbed steel bar and concrete is outstanding. In reinforced concrete structure, the width of black iron wire processing crack is smaller than that of circular steel bar, even than that of hot rolled thread steel bar. Therefore, it is used in the component, which fundamentally eliminates the phenomenon of steel wire sliding and damage, and improves the load bearing ability and crack resistance ability of the component end.
The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.
Hot plating wire mixed rare earth and aluminum elements, make zinc liquid fluidity, more uniform coating, but also reduce zinc consumption. Hot-dip galvanized wire has better protective properties than cold galvanized wire, which makes it widely used in chemical experiment equipment. Hot plated wire coating is thick, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.
Hook mesh is woven with silk core hook, the mesh is uniform, flat, beautiful and generous net width, thick wire diameter, not easy to corrosion, long life, simple weaving, beautiful and useful. It is widely used to raise chickens, ducks, geese, rabbits and zoo pens. Mechanical equipment protection, highway guardrail, sports venues purse Seine, road beautification with protective net. The screen in the manufacture of a box shaped container, filled with stone cage, can be used to maintain and support the seawall, hillside, road and bridge, reservoirs and other civil engineering.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
Large coil galvanized wire in the zinc immersion distance debugging, keep the original speed unchanged, according to t= KD to determine the zinc immersion time (1), where: t is the zinc immersion time is constant, take 4-7D is the diameter of steel wire mm, and then estimate the zinc immersion distance. By adjusting the zinc dip distance, the zinc dip time of steel wire of various specifications can be shortened by 5s on average. In this way, the zinc consumption per ton of steel wire decreases from 61kg to 59.4kg.
Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
Large roll galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Large roll galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics.
Now it is more used in the binding of the construction industry. Compared with ordinary wire, it is also softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, saving a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved. The material properties of annealed wire can meet different processing needs.
The fence effect of the barbed wire installation can be recognized by the majority of customers, its advantages are as follows: First of all, for some of the original protective device barbed wire because of the convenience of installation, the installation process is very simple, only need to fix the barbed wire column, and then gradually install the barbed wire according to the hook on the barbed wire column.
Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.
